CO2 emissions caused by surfing the web could be about to bite us in the behind
How much CO2 did you create in finding this site and reading these words? How much will I have produced by the time I have finished writing this article?
Before today it isn’t something that I would have really considered, past the energy consumption of my PC and other computer peripherals, of course. And I have been looking for the right eco gadgets to purchase that help me cut down on those emissions (eco reviews on this subject are forthcoming.)
But I never gave a thought to the apparatus that makes the internet possible, that is powered up 24 hours a day, 7 days a week. Until now.
According to Jonâ??s Swaineâ??s article in the Telelgraph today
â??[m]aking two internet searches through Google produces about the same amount of carbon dioxide as boiling a kettle, it has been estimated.â?ťâ??Googling has ‘a very definite environmental impact’ according to research conducted by a physicist from Harvard Universityâ?ť

“Google are very efficient but their primary concern is to make searches fast and that means they have a lot of extra capacity that burns energy,”
But of course it’s not just Google causing all this CO2 - this is just a part of increased alarm about the relatively little-known environmental impact of computer and internet use.
‘According to Gartner, an American research firm, IT now causes about two per cent of global CO2 emissions and its carbon footprint exceeded that of the world’s aviation industry for the first time in 2007.
Google claimed that the number was “many times too high” and one Google search is equivalent to about 0.2 grams of CO2, saying:
“We are among the most efficient of all internet search providers.”‘

So what can we do? Must we stop using the internet? Should we ration ourselves to a certain amount of time per day? Perhaps we should. It’s not welcome news, that’s for sure, but part of the solution to global warming is about us weaning ourselves off our energy addiction and looking for cleaner sources of energy.
An article in The Times, “How you can help reduce the footprint of the Webâ?ť, offers additional steps that can be taken by web consumers:
â??[Y]ou can make a difference. Over the years, Internet users have become accustomed to demanding certain levels of service from the websites that they visit. It is now de rigueur for e-commerce sites to present badges certifying that their credit card processing systems are secure.
Savvy users even know to watch for certification that sites they visit are safe from hacker attacks and that have audited privacy policies to protect their identities.Websites now need to be put under pressure to clean up their environmental impacts too and demonstrate that their sites are as green as they can be.â?ť
Which begs the question, what can website owners do to satisfy their users that they are making sure that their sites are eco-friendly? Dr Alexander Wissner-Gross, from whom a great deal of this information on the harmful emissions generated by surfing the internet has come, is a physicist & Environmental Fellow at Harvard University.
